Cartsaver COD & OTP and Blacklist Customer are evenly matched on rating (5.0★ vs 5.0★) — the differentiator comes down to pricing fit, feature breadth, and which app's interaction pattern suits your team's workflow.
Pricing entry tiers: Cartsaver COD & OTP at Free plan available, Blacklist Customer at Free trial available. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (seats, usage volume, integrations) varies.
Recommended evaluation path: install both apps' free tiers (where available) and run them in parallel on a small cohort for 7-14 days before committing. The data tables below show the per-feature breakdown — for most merchants the deciding factor will be a single integration or workflow detail that's hard to compare from listing pages alone.
This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical Shopify App Store listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.
